[Getting the cure back to the Bastion is their priority, and Zuko's encouraged by how fast Tobias seems to think he can move, but she doesn't want to lose anyone here either.

And she's fully expecting to run into more trouble than just an injured woman. In her experience, explosives tend to signal bad guys. She knows, she's been the bad guy who got signalled. She nods to Zahi and then turns to Aoi.]

Keep close to me unless I tell you otherwise. Someone probably set those explosives; we don't need to charge into trouble.

[Since Aoi seems to have even more trouble with 'look before you leap' than Zuko does.]
